" To simplify the description of the invention, the invention is illustrated by a typical example of production described by fourdriners and their stabilization by heat treatment «

Fourdrinier treated according to the following description have a stability of dimensions and temperature and resist a thrust also have a uniform porosity, since the number of yarns is always uniform «. The cross threads are always in the right. The angle to the fabric body and the longitudinal yarns are set. For all of these reasons, the finished fabric has the ability to to avoid creasing 'All these properties are so pronounced that such fabrics are in many respects' are superior to the previously used metallic Fourdrinier.

Since the fabrics that are treated according to the invention, are endless, so they require special treatment and

Thus, the inner portions of the tension chains 62 and 64, which lead backward from the loose sprockets 116 and 118 to the drive sprockets 86 and 88, are kept parallel and at the desired spacing so that the fabric is kept under constant transverse tension while the lower Trumm 14b in the i ^'! igureh view 1 and 2 to the right bev / egtwird "....

The change in pressure in the hollow body 128 can be sensed by any suitable linear direction, so a hydraulic ^ gsx system (not shown) which in turn pivots the I ¹ ort sat ζ 104, thereby maintaining a constant relationship between the opening 132 and the edge I4b of the tissue exerts sufficient force on the extension 104 so that it is held in the desired angular position, v. o by the tissue can be increasingly stretched to a width that it can have when opening through the opening 132 this width is scanned that they _; ~ o the CiUerexns division of the tensioning chain 62 must accept _o

From the above description of a preferred embodiment

In the form of the device, it can be seen that this is a new combination of spaced, parallel! If stresses relative to the structure of woven fabric are correctly related, this can be stabilized in the special conditions necessary to obtain the desired final quality. If an unstabilized fabric is only stretched in the longitudinal direction, then there is an elongation and a verclimälerung and the number of yarns changes.

The number of yarns running in the longitudinal direction becomes higher, while the number of yarns running in the transverse direction becomes smaller. This is because the longitudinal tension stretches the longitudinal yarns and bends the transverse yarns at each crossing point or increases the curvature in the case of weaving processes which are extremely carefully monitored, certain unavoidable changes in the weight or other properties of the yarns occur, as well as corresponding changes in the tension under which they are woven, if the yarns therefore only move in one direction of the yarn during one The final oaer strengthening work process ι before opension are set, then the final number of yarns of the fabric at v.uitoni does not eat enough for each section of the width and year, so that the exact guidelines for certain end users are fulfilled, Lei of the production must be used by Fourdrinier, ax to produce certain grades of paper Very high requirements regarding uniformity and porosity are set. When carrying out the invention, the fabric is gradually moved through a zone in which it is controlled in both gaskets and in which it is stabilized =.

Us is a special feature of the present invention, that the tissue to be treated is subject to constant length and width during all critical phases of the treatment Control is kept »juei this typical example is running the wavy warp yarn across the fabric and there the fabric If used as a fourdrinier wire, it is desirable to preserve the cords in the warp yarns and those in the longitudinal direction

"To make running weft threads as straight as possible» Off For this reason the fabric is brought to the final width "so that the arranged number of weft yarns is obtained, whereby this is done at a time when the longitudinal tension is slightly less than it is required to put the tissue on the final length to take off ". During this time they are under Weft yarns with relatively lower tension are free for a successful bend, while the warp yarns are increasingly taut which has the consequence that the yarn count of the weft yarns uniform across the width of the fabric. except for the The number of yarns in which the fabric is solidified is reduced. Then the tissue is put in under increasing tension Set lengthways so that all the weft yarns are practically straightened »While the weft yarns gradually stretch, becomes the tension of the warp yarns in uniform stages over increases the width of the fabric, thereby reinforcing its Y / ellen without the risk of local irregularities being produced either in the weft or warp yarn count,

which by, a slight advance change in the procedure and the door direction according to the Uriinöung can be reached. In the case of a fabric, for example, »it is initially woven as a flat sheet Before that, is that spliced or connected in other ways has been to form an endless belt, the warp yarns run in the longitudinal direction »x! s it may be desirable to have the waves, to reduce or eliminate in the warp yarns and the Waving Lehuss yarns before stabilizing the fabric will. In such a case, the -uängs voltage would apply the transverse tension applied in a predetermined manner so that one receives the desired final training. "

The fabric is preferably cut to its final width while it is still in the Lias chine, since in the I-QtJ chin ο the edges can be cut more precisely ) or a circumferential bcime id knife (not shown) is used so that one edge can be cut and then the other, or two such devices are used so that both edges can be cut at the same time or the devices can be used under the machine, Z.3. between the last heater and the roller 12 "Alternatively, such a .._ _Λ. apparatus or device s against the surface elnejr 'of the fold 12 or 10 act, if What is required is “In any case, the middle part of the fabric is cut to the arranged width and the waste edge parts can then be removed from the
